Sterling silver is an alloy of silver and other metals that are added to improve the silver's durability and strength. When your sterling silver jewelry tarnishes from oxidation, it can appear dull and gray. With a little preparation, you can make your own silver cleaner using products you already have in your home and bring out the shine and color of your sterling silver jewelry without spending money on packaged jewelry cleaner.
